My friend lost her hair to cancer and went to a wig maker to discuss her requirements.
Her real hair wig was almost exactly the same as her hair, only difference was the wig hair was a little bit thicker. It was the same colour and length and she could style it the same way. It cost her £650 
She said it gave her so much confidence and she was able to return to work when she felt well enough and wore it everyday. You really wouldn’t have known it was a wig unless she told you.
She did make me laugh when she said one day she couldn’t be bothered to wash it properly, so had popped it in a net bag in the washing machine. She put it out on the garden table, on the polystyrene head to dry naturally. A little while later she could her someone talking in the garden, she peeped out and saw her elderly neighbour chatting away to her from his garden. From where he was it must have looked like she was sitting in the garden chair at the table.
She said she didn’t dare go out, but had to stifle her giggles when he said ‘well lovely to chat Sue, even if you’re not in the mood to talk today. I hope you’re feeling well otherwise.’ And off he went. 
My Mum also lost her hair to cancer and the hospital offered her a wig. They gave her a catalogue to choose from and she made her choice. She wasn’t given any help or advice though to choose and my daughter and I weren’t at the hospital at that time so didn’t know anything about it. She was quite poorly and not quite with it at that time.
By the time it arrived, Mum had been discharged and the hospital sent it on to her at home. She was so excited when it came and asked us to go out of the room for 5 minutes, as she had a surprise for us.
We walked in to my Mum sporting a ginger wig and looking like Anne Robinson, usually she had salt n pepper hair! It was a lovely Racquel Welsh hairpiece but didn’t suit her at all. After we’d stopped giggling, she explained she thought she’d go back to her original colour from when she was younger - but realised it was a mistake as soon as she saw herself in the mirror.
We did have a giggle about it but must admit she wasn’t impressed when we told her she was the weakest link! Sadly, she’s passed now but we always remember that wig which ended up staying in its box forever more.
